What does an angle mean?

In Euclidean mathematics, a tilt is a shape consisting of two sides, or cylindrical faces, that separate at the wall's centre and its apex. Two rays may come together at their intersections to create an angle. Another result of two things interacting is an angle. They are characterized as dihedral angles. Two line beams can be arranged in different ways at their extremities to produce a two-dimensional curve.

Here,

A small pattern block is a geometric structure made up of six congruent isosceles triangles organised around a regular hexagon with six equal-length sides.

Two of the angles in an isosceles triangle are identical in size, while the third angle varies.

We need to first create a frame of reference in order to determine how many unit angles the smaller angle of a small pattern block turns through.

Assume that we begin by placing the little pattern block in its initial location with one of its sides vertically aligned.

This results in one of the isosceles triangles being vertically aligned after turning the block.

The smaller angle will therefore rotate through one unit angle each time if we continue to rotate the small pattern block anticlockwise by one-sixth of a complete revolution for each subsequent turn.

Amanda was given the following polynomial and asked to factor completely. Find the errors that she made and explain how to fix her errors.

Answers

Answer:

The error in Amanda's calculation is in line 2, where she incorrectly subtracted 6x instead of adding 6x, as well as incorrectly subtracting 24 instead of adding 24.  Amanda also omitted the addition sign in line 3 of her calculations.

Step-by-step explanation:

To factor a quadratic polynomial in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.

Therefore, for the given polynomial 4x² + 22x + 24:

⇒ ac = 4 · 24 = 96

⇒ b = 22

The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.

Therefore, the factor pair that sums to 22 is 16 and 6.

Rewrite b as the sum of these two numbers:

⇒ 4x² + 22x + 24

⇒ 4x² + (16 + 6)x + 24

⇒ 4x² + 16x + 6x + 24

Therefore, the error in Amanda's calculation is in line 2, where she incorrectly subtracted 6x instead of adding 6x, as well as incorrectly subtracting 24 instead of adding 24.  Amanda also omitted the addition sign in line 3 of her calculations.

The correct calculation is as follows:

   4x² + 22x + 24

⇒ 4x² + 16x + 6x + 24

⇒ 4x(x + 4) + 6(x + 4)

⇒ (4x + 6)(x + 4)

Given :-

A polynomial 4x² + 22x + 24 .

To find:-

The mistakes made by Amanda and how to fix the mistakes.

Answer:-

Given polynomial to us is ,

[tex]\implies 4x^2 + 22x + 24 \\[/tex]

With respect to the standard form of polynomial ax² + bx + c , we have;

a = 4 and c = 24

Step 1 :- Split the middle term into two parts p and q such that p × q = a × c and p + q = b

Such two numbers are 16 and 6 .

Hence, we can rewrite it as ,

[tex]\implies 4x^2 + 16x + 6x + 24 \\[/tex]

But Amanda wrote [tex] 4x^2+16x - 6x + 24[/tex] , so she made a mistake here by writing +6x as -6x .

a spherical snowball is melting in such a way that its diameter is decreasing at rate of 2 cm/min. at what rate is the volume of the snowball decreasing when the diameter is 6 cm?

Answers

The rate of decrease of volume of the sphere when its diameter is 6 cm is -96π cubic cm/min.

Given that the snowball is a sphere, we can use the formula for the volume of a sphere.

The formula for the volume of a sphere is

V = 4/3 πr³

We need to find out the rate of decrease of volume when the diameter is 6 cm.

To find the rate of decrease of volume, we need to differentiate the above formula. Differentiating the above formula w.r.t. time, we get

dV/dt = 4/3 π(3r²)(dr/dt)

Where r is the radius of the sphere and dr/dt is the rate of change of the radius.

Let d be the diameter of the sphere. Then we can write,r = d/2

Also, given that dr/dt = -2cm/min

Substituting the values in the equation for the rate of decrease of volume,

dV/dt = 4/3 π(3(d/2)²)(-2) = -8π/3 d²

As the diameter of the sphere is 6 cm, d = 6 cm.Substituting the value in the equation above, we get

dV/dt = -8π/3 (6)² = -96π cubic cm/min

property?

Answers

Janella recognizes a gain of $36,000 and her basis in the distributed property is $54,000.

Janella's basis in her partnership interest is $120,000, which includes her share of partnership debt. When the partnership pays off its debts and liquidates, Janella receives a proportionate liquidating distribution consisting of $42,000 cash and inventory valued at $24,000 (adjusted basis to the partnership = $20,000).

To calculate Janella's recognized gain or loss, we need to compare her basis in the partnership interest to the fair market value of the distributed assets.

The fair market value of the distributed assets is $42,000 (cash) + $24,000 (inventory) = $66,000.

The amount of the loss is the excess of her basis over the fair market value of the distributed assets, which is $120,000 - $66,000 = $54,000.

To determine Janella's basis in the distributed property, we need to adjust her basis in the partnership interest by the amount of the liquidating distribution she received.

Janella received a total liquidating distribution of $42,000 cash + $24,000 inventory = $66,000. Her share of partnership debt was $150,000, and the partnership paid off all its debts, so she no longer has any debt basis.

Janella's distribution of $66,000 exceeds her adjusted basis of $30,000 by $36,000. She recognizes a gain of $36,000. Therefore, Janella's new basis in the distributed property is $120,000 - $66,000 (liquidating distribution) = $54,000.

|13w - 5 + w + 3| - 5 + w + 3 > 5|14w - 2| - 2 > 5|14w - 2| > 7

Now we can split the inequality into two cases: 14w - 2 > 7 and -(14w - 2) > 7. Solving each case for w gives:

14w - 2 > 7

A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1850 pounds in a westerly direction. The other bulldozer pushes the piling with a force of 3250 pounds in a northerly direction. What is the direction of the resulting force upon the piling, to the nearest degree?
I need some help with this yall​

Answers

The direction of the resulting force upon the piling is approximately 298.85 degrees

We can use vector addition to find the direction of the resulting force. Let's call the force exerted by the first bulldozer F1, and the force exerted by the second bulldozer F2. We can represent each force as a vector with a magnitude and direction.

F1 has a magnitude of 1850 pounds and points in a westerly direction. We can represent it as a vector (-1850, 0).

F2 has a magnitude of 3250 pounds and points in a northerly direction. We can represent it as a vector (0, 3250).

To find the resulting force, we need to add these two vectors. We can do this by adding the x-components and the y-components separately.

The x-component of the resulting force is -1850 (from F1) plus 0 (from F2), which is -1850.

The y-component of the resulting force is 0 (from F1) plus 3250 (from F2), which is 3250.

So the resulting force is a vector with components (-1850, 3250). We can find the direction of this vector by taking the inverse tangent of the ratio of the y-component to the x-component.

tan(theta) = (3250) / (-1850)

theta = -61.15 degrees

The negative sign indicates that the resulting force points to the southwest. To get the angle in the range of 0 to 360 degrees, we can add 360 degrees to the angle if it is negative.

theta = 360 - 61.15

theta = 298.85 degrees

1. 5 ft

What is the total area of the gray sections of the target, to the nearest square inch?

A 452 square inches

B. 565 square inches

C 678 square inches

D. 1017 square inches

Answers

The total area of gray sections of the target is  1017 square inches. The correct option is (D).

To find the total area of the gray sections of the target, we need to first find the areas of the gray rings. We can do this by subtracting the area of the smaller circle from the area of the larger circle for each ring.

The area of a circle is given by the formula A = πr^2, where r is the radius.

For the outer gray ring, the radius is 1.5 feet. So, the area of the gray ring is:

A_gray_outer = π(1.5)^2 - π(1)^2

= 7.06858 - 3.14159

= 3.92699 square feet

For the middle gray ring, the radius is 1 foot. So, the area of the gray ring is:

A_gray_middle = π(1)^2 - π(0.5)^2

= 3.14159 - 0.78540

= 2.35619 square feet

For the inner gray ring, the radius is 0.5 feet. So, the area of the gray ring is:

A_gray_inner = π(0.5)^2 - 0

= 0.78540 square feet

The total area of the gray sections of the target is the sum of these three areas:

A_total_gray = A_gray_outer + A_gray_middle + A_gray_inner

= 3.92699 + 2.35619 + 0.78540

= 7.06858 square feet

To convert this to square inches, we multiply by the conversion factor (12 inches/foot)^2:

A_total_gray = 7.06858 * (12)^2

= 1016.7048 square inches

Rounding this to the nearest square inch gives:

Answer:

343 cubic meters.

Step-by-step explanation:

To find the volume of a cube given its surface area, we need to first find the length of one of its sides.

The formula for the surface area of a cube is:

SA = 6s^2

where SA is the surface area and s is the length of one of the cube's sides.

We are given that the surface area is 294 square meters, so we can set up the equation:

294 = 6s^2

Simplifying, we get:

49 = s^2

Taking the square root of both sides, we get:

s = 7

So the length of one of the cube's sides is 7 meters.

To find the volume of the cube, we use the formula:

V = s^3

Substituting in 7 for s, we get:

V = 7^3 = 343

Therefore, the volume of the cube is 343 cubic meters.

Answer:

343m³

Step-by-step explanation:

Surface area of a cube is A = 6a²

6a² = 294

Divide both sides by 6

a² = 49

Square root of both sides

a =7

Substitute the value of a into volume

Volume of Cube V = a³

V = 7x 7x7

V = 343m³

Answers

Tom is working two jobs to save money for prom, walking a neighbor's dog for $6.50 an hour and washing cars for $7 an hour, to make at least $91.

Tom is working to put money aside for the prom.. His mother has instructed him that in order to keep up with his schoolwork, he may only work a maximum of 15 hours each week. Tom has made the decision to wash cars for $7 per hour and walk his neighbor's dog for $6.50 per hour in order to achieve this aim. For his prom expenditures, he will need to earn at least $91. He must put in a maximum of 13.2 hours of work to earn $91. This implies he can stroll a dog for 8.4 hours and wash vehicles for 4.8 hours. He can also decide to simply perform one job; but, in order to earn the appropriate amount, he would need to walk his neighbor's dog for 12 hours.

an escalator can move 30 people per minute from the main level to the upper level. How long would it take to use the escalator to move 100 people?

Answers

Answer:

3.33 minutes

Step-by-step explanation:

first know that the escalator can move 30 people in 1 minute.

then, we can write in a mathematical expression as:

30 people = 1 minute

100 people = ? minutes.

cross multiply, i.e. 30×? = 100×1

therefore, ? = 100/30

? = 3.33 minutes.

therefore, it's going to take 3.33 minutes for the escalorr to take 100 people.

Answer: line A

Step-by-step explanation:

2x is the slope and -1 is the y-intercept
2x for the slope, also 2/1x (meaning rising up 2 places for every one place on the x axis).
Line A is the only line who has 2x for the slope.
ANSWER: LINE (A)

Answer:

Line a

Step-by-step explanation:

The equation is y= 2x - 1 so....

Slope = 2

Y-intercept = -1

Slope can be put as Rise/ Run ( up/ side)

This means the slope can be written as 2/1

Line a has a slope of 2/1 from the point -1 so the answer is line a

In its January 25, 2012, issue, the Journal of the American Medical Association (JAMA) reported on the effects of overconsumption of low, normal, and high protein diets on weight gain, energy expenditure, and body composition. Researchers conducted a single blind, randomized controlled trial of 25 U. S. Adults. The subjects were healthy, weight-stable, male and female volunteers, aged 18 to 35 years. All subjects consumed a weight-stabilizing diet for 13 to 25 days. Afterwards, the researchers randomly assigned participants to diets containing various percentages of energy from protein: 5% (low protein), 15% (normal protein), or 25% (high protein). The subjects were not aware of the specific protein level diet to which they were assigned. On these diets the researchers overfed the participants during the last 8 weeks of their 10 to 12 week stay in the inpatient metabolic unit. The goal was to investigate the effect of overconsumption of protein on weight gain, energy expenditure, and body composition. What is the purpose of random assignment in this experiment?


a. To generalize the experiment results to a larger group

b. To avoid bias

c. To produce treatment groups with similar characteristics

d. To control for confounding variables

Answers

Random assignment in this experiment is important to avoid bias.

By randomly assigning participants to diets with different levels of protein, the researchers are ensuring that any differences in outcomes are due to the diet, and not because of any individual characteristics of the participants. Random assignment helps to ensure that the groups being compared in the experiment are similar and that any differences seen in outcomes are due to the protein level and not other factors. Random assignment helps to eliminate any bias that could be introduced if the participants were assigned to diets based on their own characteristics. This helps to ensure that the results of the experiment are valid and accurate.

In a binomial situation, n = 4 and π = 0.35. Find the
probabilities for all possible values of the random variable,
x. (Round your answers to 4 decimal places.)

Answers

The prοbabilities fοr all pοssible values οf the randοm variable x are:

P(x) = 0.1785 P(x) = 0.3911 P(x) = 0.3462 P(x) = 0.1124 P(x) = 0.0118.

Hοw likely is it that twο randοm variables will οccur?

The jοint prοbability is the likelihοοd οf twο (οr mοre) events. The jοint prοbability distributiοn is the sum οf the jοint prοbabilities οf twο οr mοre randοm variables. Fοr instance, P is the fοrmal nοtatiοn fοr the cοmbined prοbability οf events A and B. (A and B)

We can use the fοllοwing fοrmula tο find the prοbabilities fοr all pοssible values οf the randοm variable, x, in a binοmial situatiοn where n = 4 and = 0.35:

P(x) = (n chοοse x)[tex]* \pi ^x * (1-\pi)^{(n-x)[/tex]

where "n select x" is the binοmial cοefficient, which equals n! / (x! * (n-x)!).

Then, fοr x = 0, 1, 2, 3, and 4, we can cοmpute P(x) as fοllοws:

P(x=0) = (4 chοοse 0) [tex]* 0.35^0 * 0.65^4 = 0.1785[/tex]

P(x=1) = (4 chοοse 1) [tex]* 0.35^1 * 0.65^3 = 0.3911[/tex]

P(x=2) = (4 chοοse 2) [tex]* 0.35^2 * 0.65^2 = 0.3462[/tex]

P(x=3) = (4 chοοse 3) [tex]* 0.35^3 * 0.65^1 = 0.1124[/tex]

P(x=4) = (4 chοοse 4) [tex]* 0.35^4 * 0.65^0 = 0.0118[/tex]

When we rοund these numbers tο fοur decimal places, we get:

P(x=0) = 0.1785

P(x=1) = 0.3911

P(x=2) = 0.3462

P(x=3) = 0.1124

P(x=4) = 0.0118

As a result, the prοbabilities fοr all pοssible values οf the randοm variable x are as fοllοws:

P(x=0) = 0.1785

P(x=1) = 0.3911

P(x=2) = 0.3462

P(x=3) = 0.1124
